To att whom it may concern:

"f'Be it known that I, NICHOLAS F. Acxna- MAN, a `citizen of the United States, and resident of Duluth, in the county of St. Louis and State of Minnesota, have invented cer.

tain `new and useful Improvements in Means ft'xrV vRepairing Furnaces, of which the following is a specification.

This invention relates to. means for repairing furnaces.,l

One of the objects is to repair a furnace without lcooling or laying out the'same.

Another object is to provide novel means which `isinserted into 'a furnace whereby the latter'may be quickly repaired.A

Another -object vis means of which furnace .roofs may be repaired {,in. a 4manner to'meet the various requirements forsuccessful commercial use.

These and-other objects are accomplished by providing a device of the class described including means which is insertible into a furnace and which forms a support for a portion ofthe furnace being repaired.

The invention lis `illustrated on the accompanying sheet of drawings in which Figure 1 is a side elevation, parts being in section, ofta furnace, a charging machine, and my repair mechanism associated therewlth; an l y Fig. 2 is afragmentarv sectional view ofthe same taken 1n the p ane of line 2-2 of Fig. 1. v o

The. various novel features of my invention will be apparent from the'following description and drawings and will be larly ointed out in the appended claims.

Refgrring particularly to the figures of the drawings -it will be noted lthat I have shown, generally speaking, an open hearth furnace 10, a charging machine 1l, and means 12 whereby the roof of the open hearth furnace may be repaired. It is well appreciated that in the operation of furnaces of the type mentioned, it 1s frequently necessary to repair the same for the reason that the parts thereof become seriously deteriorated as a `result of being subyected to heat of extreme temperatures. lIt is a very expensive matter to cool down a furnace, or to lay itout. For this reason it is highly essential to repair furnaces while they are in operative condition. To this end I have provided my novel device whereby portions of the furnace may be repaired m a manner I Specification of Letters Patent.

y part which to provide a device by- Ma'Ns ron nEPAIaINe Fumraciis.r I

the furnace 10. In view of the fact thatthe roof of a furnace of this type is usually the needs repair most frequently, I have shown the form or supporting head 15 shaped `and arranged in a manner to facilitate the repairing of furnace roofs. However, it will be appreciated that other parts of the furnace may be repaired by any other suitable support having the required shape. It will 'be noted that this supporting head 15 is inserted into the furnace through a doorway 18 thereof, and in this instance is peel 19 of the charging deconnected to the vice 11 of any standard and well known type. After the supporting head -15 is inserted into the furnace the same may be moved longitudinally, vertically or rotated, so that the supporting surface 16 may be placed in its proper position to conform with the surface of the roof -by the usual chargin machine mechanism which is capable of giving the peel such movements. It is seen, therefore, that the supporting head 15 may be properly placed for supporting the brick of the part of the roof to be repaired. Of course it is to be understood that this repairing device need not necessarily be supported by the peel 19 or any other part of a charging machine, for it is readily apparent that the same may be supported and operated manually or by other suitable mechanism which is not associated with charging machines. However, in view of the fact that most furnaces of this type are provided with charging machines I choose to illustrate my inventlon in connection therewith. I

In view of the fact that the furnaces of this nature are subjected to' extremely high temperatures` it is essential that my repair .device'be protected against such excessive temperatures. To this end I have provided means for maintaining parts of this device relatively cool, or at least sufficiently cool to accomplish the desired results. It will be note that I have provided a water mlet Patented June 25, 1918. Application led September 6,1917'. Serial N o. 190,076. I
